PATENT CLOTH ES-WRINGER CLAMP.

SPECIFICATION forming part of Letters Patent No. 594,454, dated November 30, 1897. Application filed April 30, 1897. Serial No. 634,531. (No model.)

To a/ZZ whom t may concern:

Beit known that I, HOWARD U. ACKERMAN, a citizen of the Unit-ed States, residing at Indianapolisin the county of Marion and the State of Indiana, have invented certain new and useful Improvements in Olothes-VVringer Clamps; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide a clamp for clothes-wringers whereby. the wringer can be securelyfastened to galvanized-iron tubs, as well as to wooden tubs and tubs the sides of which are made out of a iibrous composition. The shrinking of the staves of a wooden tub, which causes the hoops to loosen and the tub to fall to pieces, has created a demand for a galvanized-iron tub, whichwould be more durable; but a serious disadvantage attending the use of this tub arises from the difculty in clamping the clothes-wringer to the thin metal forming the sides. This difficulty I have overcome by the mechanism illustrated in the accompanying drawings, and have also provided a clamp which can be used on other kinds of tubs in A COlIlmOIl USG.

the other portions of the wrin ger are omitted.

A represents a portion of a sheet-metal tub having its upper edge turned over a stiftening-wire B. O is the clothes-wringer, having the spring O' to force the rollers together, all of said parts being of well-known form.

D represents my improved clamp, which is fastened to the spring C' by means of the bolt c in the usual manner. There are -two kof the springs O', one at each end v`of the wringer, and I use two clamps, or one for each spring, as is usually employed. As these clamps are exact duplicates of each other only one will be shown and described.

The body portion of the clamp D comprises the arm D', whichis inserted insideof the tub and rests against the side of the tub, and the outside ears CZ and d', which are integral with the arm D', but are separated therefrom in theirlower parts by the under side tapering notch E, whereby the combined parts, with this under side notch, form a hook by which the attached wringer can be hooked onto the sides of the tub. In many cases the hook as here described is sufficient to secure the wringer without the application of any specifi-c clamping device; but where the wirestiffened edge of the tub is toosmall in diameter to be securely caught and wedged in the tapering notch E, which condition is illustrated in the drawings, a clamping device becomes essential.

The ears d and d are separated sufciently to allow the lever F to be inserted between them, and this lever is hinged to the ears by means of the cross-pin f in the manner as clearly shown in the drawings. 'Ihe upper end of the lever is notchedto fit the wired edge of the tub, and the lower end is pro'- vided with a threaded opening through which the screw-threaded wing-bolt G is screwed. The inner end of the wing-bolt is forced against the outside of the tub and will preferably be provided with a plate g, connected to the bolt by a swiveljoint whereby'the Aplate will remain stationary when the bolt is turned and prevents mari-ing the tub by the action of the bolt end. The plate will preferably be faced with rubber g' for additional protection to the tub. By forcing the lower end of the lever out With the screwthe upper end of the lever Will be forced against'the Wired edge of the tub, vand the accompanying upward pressure against the ears will forcethe arm D against the tub on the inside, thereby clamping the Walls of the tub tightly between the arm and the outside bolt.

Inorder that the clamp maybe used without change for fastening the wringer to tubs made with wooden staves and which are of much greater thickness than metal tubs, I provide an outward bend in the lever F at a point below the ears sufficient to allow the stave to be inserted between the lower part of the lever and the arm D, the wing-bolt IOO being previously screwed out, and then by tightening up the bolt against the tub the latter will be securely held.

Fiber tubs are intermediate in thickness between a Wooden tub and a metal one. The edge of the fiber tub will enter the wedge shaped notch E, but will not extend up into contact with the top of the lever. It will be locked iu place by screwing up the wing-bolt in the same manner as described for the wooden tub. Vith both the wood-stave and the ber tubs the top end of the lever bears against the arm D', and thereby gives eflicieney to the action of the screw.

This clamp will be applied to wringers having a wooden frame, and it is not desired to limit the construction to the use of a screw to operate the lever, for it is very evident a cani could be applied in place of the screw, which would force the outer end of the lever out and accomplish the same result which is secured by the screw.

Having thus fully described my invention,

what I claim as new, and wish to secure by Letters Patent of the United States, is

A clamp for fastening clothes-wringers to tubs comprising a body portion having au arm to go on the inside 0f the tub, ears integral with the arm but partially separated therefrom by an under side tapering notch to receive the side of the tub, in combination with a lever pivotally secured to the ears and notched at its upper end to engage the tub in the manner as described and bent outwardly below to receive the staves of a wooden tub, and means for forcing the lower end of the lever in an outward direction, all substantially as described and for the purposes specified.

ln testimony whereof I aflix my signature in presence of two witnesses.

IIOVARD U. AOKERMAN.
